Ambiguity and conflict in sentencing research: Partial resolution through crime-specific analysis
Journal of Criminal Justice, 1985Prior research on factors influencing sentence severity has produced ambiguous findings. To resolve some of this ambiguity, a crime-specific approach to data analysis is proposed and tested. The research sample consists of 468 convictions resulting from 619 indictments for the crimes of murder, rape, aggravated assault, and robbery.

Partial ambiguity resolution for reliable GNSS positioning — A useful tool?
2016 IEEE Aerospace Conference, 2016In differential global navigation satellite system positioning applications with short to moderate observation time spans, carrier phase ambiguity resolution is required to obtain precise coordinate estimates. Depending on the length of the baseline, differential atmospheric delays between the two receivers may have to be considered, thus weakening the

Single-Frequency GPS/BDS Combined RTK Positioning with Partial Ambiguity Resolution
2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019Aiming at the problem that the ambiguity of carrier-phase is usually more difficult to fix and the positioning result is less effective when using low-cost receiver for real-time kinematic (RTK) positioning, a combined adaptive partial ambiguity resolution (CA-PAR) algorithm is proposed in this paper. The algorithm adaptively adjusts the boundary value

Research on Fast RTK GNSS Algorithm Based on Partial Ambiguity Resolution
2017The key of GNSS RTK algorithm is the fast and reliable double difference integer ambiguity resolution. Currently widely used algorithm is the LAMBDA method based on the ambiguity search algorithm. But the search efficiency of LAMBDA method is gradually reduced with the increase of the degree of ambiguity.

Model and Data Driven Partial Ambiguity Resolution for Multi-Constellation GNSS
2014The goal of carrier-phase ambiguity resolution is to exploit that the carrier-phase observations start to act as very precise pseudoranges. With the development of modern GNSS (GPS, BDS, Galileo, Glonass), more than 30 satellites are visible, however, it might be impossible to reliably fix all the ambiguities due to the computation time.

IEEE/ION Position, Location and Navigation Symposium, 2010
This paper evaluates the benefit of the partial availability of GPS satellites with L2C signal capability in estimating the ionospheric delay using the dual-frequency L1/L2 code and phase measurements using real data. Compared to the strategy of estimating one slant ionospheric delay (SID) for each satellite, a simplified single differential zenith ...

Knowledge of differential inter-system biases (DISBs) is critical to integrate observations from mixed GNSS. If the corresponding DISB could be calibrated in advance, only one pivot satellite is sufficient for ambiguity resolution on overlapping frequencies, which is the so-called tight combining (TC) strategy. Considering that GPS and Galileo transmit
